TECHNICAL FIELD

The present disclosure relates to an information processing apparatus, an information processing method, and a program. More specifically, the present disclosure relates to an information processing apparatus, an information processing method, and a program by which to display information on real objects existing in the vicinity of the information processing apparatus on a display unit (display) on the basis of the position and direction of the information apparatus.

BACKGROUND ART

Recently, smart phones, tablet terminals, or wearable terminals such as an eyeglass-type display, and the like have become widespread and these terminals are utilized by a large number of users.

Most of these terminals include not only the communication function but also the camera function by which to display shot images on display units. In addition, the display units are capable of displaying not only the shot images but also various kinds of information received via networks such as web pages accessed via networks, for example.

Further, there are terminals capable of acquiring information associated with positional information from web sites and displaying the same in accordance with geostationary earth orbit (Geo) information set as attribute information on camera-shot images and positional information acquired by the global positioning system (GPS) function of mobile terminals, for example.

Besides, Patent Document 1 (Japanese Patent Application Laid-Open No. 2011-028763) discloses a configuration in which such information related to shot images is superimposed and displayed on the shot images, for example.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention

There are many conventional techniques for configurations that allow the related information on shot objects to be superimposed and displayed on a terminal on the basis of the positional information such as GPS and Geo information.

By using data in which registration information on various facilities is accurately associated with the positions of the facilities to detect the position and inclination of the user terminal shooting and displaying objects and perform a control to move the related information in synchronization with the movement of the object on the display unit, it is possible to superimpose and display the registration information in accordance with the positions of the facilities.

However, according to the conventional methods, the related information is superimposed and displayed on the shot video, following the positional relationship between the Geo positional information in the information apparatus and the Geo positional information in the registration information and the position of an subject recognized in the video shot by the camera on the shot video, by a program in the information processing apparatus. Accordingly, the size and color of text superimposed and displayed in accordance with metadata in the registration information can be changed. However, it is difficult to change the registration information to be displayed with user behavior, the context (situations) of the information terminal, or a change in the behavior or the context as a trigger, and control the display method (the size and position of the characters, animation, and others).

For example, it is difficult to perform flexible processes on the basis of the user physical information (heartbeat, pulse, and the like) obtained from the sensor in the information terminal and the information from the temperature sensor such that, when there is an isotonic drink vending machine in the vicinity of the information terminal, although it is not seen in the camera-shot video, the registration information related to the vending machine is displayed to encourage the user to drink liquid.

The present disclosure is devised in light of the foregoing problem, for example, to display information on a registered and set real-world point (point of interest (POI)) at the occurrence of an event in accordance with the context (situations) determined from the positional relationship between the user terminal such as a smart phone and the position of the point and various kinds of information obtained from the user terminal as a trigger. For example, an object of the present disclosure is to provide an information processing apparatus, an information processing method, and a program by which to allow information display in various manners such that, when the position and inclination of the user terminal are changed in accordance with the user's motion and the like, the status of the user behavior (walking, running, riding a train, or the like) is considered in addition to the amount of the change to change the information to be displayed and the method of display (the size and display position of the text).

[1. About Configuration Examples of the Information Processing Apparatus of the Present Disclosure and a System Including the Information Processing Apparatus]

First, configuration examples of the information processing apparatus of the present disclosure and a system including the information processing apparatus will be explained with reference to FIG. 1.

FIG. 1 is a diagram illustrating a configuration example of a communication system including the information processing apparatus of the present disclosure.

An information processing apparatus (user terminal) 10 is a communication terminal capable of being carried by a user such as a smart phone or an eyeglass-type terminal, for example.

The information processing apparatus (user terminal) 10 includes a communication unit, a camera (imaging unit), and a display unit, and has the functions of displaying a camera-shot image on the display unit, and superimposing and displaying information received via the communication unit on the shot image on the display unit.

The information processing apparatus 10 displays the camera-shot image on the display unit. The display image on the display unit is a real-time shot image that is currently shot by the camera. Incidentally, the processes of the present disclosure are applicable to the case in which an image previously shot and stored in a memory is read and displayed on the display unit. However, in the example described below, the currently shot image is displayed on the display unit. Incidentally, the shot image may or may not be recorded in a storage unit such as a medium.

The camera (imaging unit) and the display unit of the information processing apparatus 10 may be implemented by different devices and configured to operate integrally via communications.

The configuration in which they operate integrally via communications can be implemented such that moving images shot by the camera (imaging unit) attached to the head of the user, and position and direction information are transmitted to the smart phone (display unit) via Wi-Fi, for example.

The processes of the present disclosure are also applicable to both the case in which the information processing apparatus 10 is one physical apparatus and the case in which the information processing apparatus 10 is formed by a plurality of devices via communications.

While displaying the shot image on the display unit, the information processing apparatus 10 receives a beacon output from a beacon transmitter 20 composed of an access point (AP) in a wireless LAN or Bluetooth, for example.

The beacon is a packet storing an identifier (ID) of the beacon transmitter 20.

The information processing apparatus 10 transfers the beacon received from the beacon transmitter 20 to a search server 40 via a network 30 such as the Internet.

Upon receipt of the beacon transferred from the information processing apparatus 10, the search server 40 acquires access information (URL) registered in correspondence with the beacon transmitter identifier (ID) included in the received beacon on the basis of the identifier, and transmits the same to the information processing apparatus 10.

The access information (URL) is access information for acquiring positional information on information registration points near the beacon transmitter 20, and data including registration information, and the like.

Incidentally, in map data provided on web pages, for example, registration information setting points (points of interest (POIs)) are set as points estimated to attract interest from many people such as tourist spots and landmarks. The access information (URL) is access information for acquiring display control data including positional information on the registration information setting points (POIs), registration information, and the like.

The information processing apparatus 10 uses the access information (URL) to acquire the display control data from an information provision server 50, and superimposes and displays the registration information and the like corresponding to the registration information setting points (POIs) included in the acquired display control data on the shot image on the display unit.

That is, the information processing apparatus 10 superimposes and displays the positional information on the POIs acquired from the information provision server 50 and the registration information as virtual objects on the real objects shot by the camera (imaging unit) and displayed on the display unit.

The information provision server 50 provides POI display control data such as positional information on various facilities in various positions in regions and guide information on the facilities. The information provision server 50 includes a database in which the registration information is registered, and generates the display control data on the basis of the database information. The information provision server 50 returns the relevant display control data in accordance with the URL included in a request from the information terminal 10.

The information processing apparatus 10 uses the access information (URL) selected by the search server 40 to acquire the POI display control data from the information provision server 50.

The information processing apparatus 10 uses the POI display control data to superimpose and display the POI positions and the registration information on various facilities near the installation place of the beacon transmitter 20 on the camera-shot image displayed on the display unit.

A specific process example will be explained with reference to FIGS. 2(a) and 2(b).

FIGS. 2(a) and 2(b) illustrate a display example of a camera-shot image on the display unit by the information processing apparatus (user terminal) 10.

Incidentally, in the following description, a smart phone is taken as an example of the information processing apparatus (user terminal) 10. However, the example explained below can also be carried out on various user terminals other than a smart phone, such as a tablet terminal, a PC, an eyeglass-type terminal, or the like, for example.

FIG. 2(a) illustrates a landscape in a real world that includes a castle in a tourist spot. The user carrying the information processing apparatus (user terminal) 10 visits the castle in the tourist spot and sees the landscape illustrated in FIG. 2(a).

The user uses the camera function of the information processing apparatus (user terminal) 10 to shoot (a) a real-world image and display the shot image on the display unit.

The shot image displayed on the display unit is a display image illustrated in FIG. 2(b).

For example, in this state, the series of processes explained above with reference to FIG. 1 is executed. That is, the following steps (S01 to S04) are performed:

(S01) The information processing apparatus 10 transfers to the search server 40 the identification information (ID) on the beacon received from the beacon transmitter 20 such as a close access point (AP) in the real world illustrated in FIG. 2(a).

(S02) The search server 40 transmits to the information processing apparatus 10 the access information (URL) for acquiring the data including the registration information on the neighborhood of the beacon transmitter 20 on the basis of the identification information.

(S03) The information processing apparatus 10 uses the access information (URL) received from the search server 40 to acquire from the information provision server 50 the display control data such as the positional information and the registration information on the facilities near the beacon transmitter 20.

(S04) The information processing apparatus 10 uses the display control data such as the positional information and the registration information on the facilities near the beacon transmitter 20 acquired from the information provision server 50 to superimpose and display marks indicative of the positions of the facilities and the registration information as virtual objects on the shot image displayed on the display unit.

The foregoing series of steps is performed.

As a result of the execution of the foregoing series of steps, FIGS. 3(a), 3(b), 4(a), and 4(b) illustrate examples of display images displayed on the display unit of the information processing apparatus 10.

FIG. 3(a) illustrates a landscape in the real world as in the case of FIG. 2(a) explained above, and FIG. 3(b) illustrates a display image displayed on the display unit of the information processing apparatus 10 after the execution of the foregoing series of steps (S01 to S04).

At step S03, the data acquired from the information provision server 50, that is, the display control data such as the positional information and the registration information on the facilities near the beacon transmitter 20 includes information on the following two points in the real world illustrated in FIG. 3(a):

-   -   (1) Positional information and registration information on a         registration information setting point A (POI-A) 101     -   (2) Positional information and registration information on a         registration information setting point B (POI-B) 102.

The display image illustrated in FIG. 3(b) is a display image displayed with selection of (1) the positional information and registration information on registration information setting point A (POI-A) 101.

The display image illustrated in FIG. 3(b) is an image in which virtual objects described in the display control data acquired from the information provision server 50 are superimposed and displayed on the real object as the shot image.

The displayed virtual objects are the following data:

-   -   (1) Point A (POI-A) position identification mark 111     -   (2) Point A (POI-A) correspondence registration information 112

These data are displayed as virtual objects.

As described above, the display image illustrated in FIG. 3(b) is an image in which virtual objects generated on the basis of the display control data acquired from the information provision server 50 are superimposed and displayed on the real object as the shot image, that is, an augmented reality (AR) image.

The point A is a ticket center. The point A (POI-A) position identification mark 111 as a virtual object is superimposed and displayed in the position of the ticket center in the shot image as the real object.

The display position of the point A (POI-A) position identification mark 111 needs to be set on the ticket center in the shot image as the real object. This display position is decided by the information processing apparatus 10 with the use of the data acquired from the information provision server. Incidentally, the image displayed on the information processing apparatus 10 is a real-time camera-shot image that changes in accordance with the motion of the user. The display position of the point A (POI-A) position identification mark 111 also needs to be updated in accordance with the motion of the displayed shot image (real object). The display position control is also executed by the information processing apparatus 10.

Under the display control executed by the information processing apparatus 10, the display position of the point A (POI-A) position identification mark 111 as a virtual object is correctly placed on the ticket center in the shot image as the real object.

The specific steps of the display control will be described later.

Further, the point A (POI-A) correspondence registration information 112 as another virtual object is also superimposed and displayed on the shot image as the real object.

The point A (POI-A) correspondence registration information 112 includes various kinds of information on the ticket center corresponding to the registration information setting point A. As illustrated in the drawing, information on the opening hours and fees at the ticket center and the like is displayed. The information is recorded in the database of the information provision server 50, and is included in the display control data acquired in accordance with the URL provided by the search server 40 or is acquired on the basis of the display control data.

FIGS. 4(a) and 4(b) are diagrams illustrating a display image example with the use of information on another point B, that is:

-   -   (2) Positional information and registration information on the         registration information setting point B (POI-B) 102.

FIG. 4(a) illustrates a landscape in the real world, and FIG. 4(b) illustrates a display image displayed on the display unit of the information processing apparatus 10 after the execution of the foregoing series of steps (S01 to S04).

The display image illustrated in FIG. 4(b) is an image in which virtual objects as display data acquired from the information provision server 50 are superimposed and displayed on the real object as the shot image.

The virtual objects displayed are the following data:

-   -   (1) Point B (POI-B) position identification mark 121     -   (2) Point B (POI-B) correspondence registration information 122

These data are displayed as virtual objects.

As described above, the display image illustrated in FIG. 4(b) is an image in which the virtual objects generated on the basis of the data acquired from the information provision server 50 are superimposed and displayed on the real object as the shot image, that is, an augmented reality (AR) image.

The point B represents an entrance to the castle, and the point B (POI-B) position identification mark 121 is superimposed and displayed as a virtual object on the shot image as the real object at the entrance position.

The display position of the point B (POI-B) position identification mark 121 needs to be set on the entrance to the castle in the shot image as the real object. The display position is decided and controlled by the information processing apparatus 10 with the use of the data acquired from the information provision server. Specifically, the information processing apparatus 10 updates the display position of the point B (POI-B) position identification mark 121 in accordance with the motion of the shot image (real object) displayed on the display unit.

Under the display control executed by the information processing apparatus 10, the display position of the point B (POI-B) position identification mark 121 as a virtual object is always set on the entrance in the shot image as the real object.

The specific steps of the display control will be described later.

Further, the point B (POI-B) correspondence registration information 122 as another virtual object is also superimposed and displayed on the shot image as the real object.

The point B (POI-B) correspondence registration information 122 includes various kinds of information on the castle entrance corresponding to the registration information setting point B. As illustrated in the drawing, information such as the opening hours of the entrance, information on lending of guide terminals, rest room positional information, and others is displayed. The information is recorded in the database of the information provision server 50 and acquired in accordance with the URL provided by the search server 40.

[2. About the Details of a Communication Process and an Image Display Process]

FIG. 5 is a sequence diagram describing a communication sequence executed between the apparatuses illustrated in FIG. 1 and a display process sequence of an augmented reality image (superimposed image of real object and virtual objects) executed by the information processing apparatus (user terminal) 10.

FIG. 5 illustrates the beacon transmitter 20, the information processing apparatus (user terminal) 10, the search server 40, and the information provision server 50 from the left side.

The process steps will be explained below in sequence.

(Step S101)

First, at step S101, the beacon transmitter 20 outputs a beacon and the information processing apparatus 10 receives the beacon. As described above, the beacon is a packet storing the identifier (ID) of the beacon transmitter 20 and the like.

(Step S102)

The information processing apparatus 10 transfers the beacon received from the beacon transmitter 20 to the search server 40.

(Step S103)

The search server 40 receives the beacon transferred from the information processing apparatus 10, and searches the database on the basis of the identifier (ID) of the beacon transmitter 20 included in the beacon to extract access information (URL) for acquiring the data including the registration information on the neighborhood of the beacon transmitter 20.

FIG. 6 illustrates an example of data stored in the database of the search server 40. The search server 40 stores data as described in FIG. 6 in the database (storage unit), for example.

The data illustrated in FIG. 6 is composed of a correspondence list of the following two data:

Beacon transmitter identifier (ID); and

URL for acquiring beacon transmitter neighborhood facilities information.

The search server 40 receives the beacon transferred from the information processing apparatus 10, and searches the list of the data configuration described in FIG. 6, for example, on the basis of the identifier (ID) of the beacon transmitter 20 included in the beacon.

By the list search, the search server 40 acquires the access information (URL) associated with the identifier (ID) of the beacon transmitter 20 included in the beacon transferred from the information processing apparatus 10.

The access information (URL) is access information (URL) for acquiring the data including the registration information on the neighborhood of the beacon transmitter 20.

(Step S104)

Next, at step S104, the search server 40 transmits to the information processing apparatus 10 the access information (URL) acquired by the search at step S103.

(Step S105)

The information processing apparatus 10 uses the access information (URL) received from the search server 40 to acquire the data including the positional information and registration information on the facilities near the beacon transmitter 20 (virtual object display control data) from the information provision server 50.

The data transmitted from the information provision server 50 to the information processing apparatus 10 includes real-state data on virtual objects to be superimposed and displayed on the camera-shot image as the real object displayed on the display unit of the information processing apparatus 10 and display control information for the real-state data. The data will be hereinafter called virtual object display control data.

The virtual object display control data is specifically composed of the following data and the like:

-   -   (1) hyper text markup language (HTML)     -   (2) cascading style sheet (CSS)     -   (3) JavaScript (registered trademark).

The HTML is data indicative of a basic structure of the virtual objects displayed on the display unit of the information processing apparatus 10. Although there are various kinds of HTML data, HTML 5 is usable, for example.

The CSS is a style sheet that defines the display formats, colors, shapes, and others of the virtual object configuration data defined by the HTML, which is data defining the style of the virtual objects displayed on the display unit of the information processing apparatus 10.

The JavaScript (registered trademark) is a display control program that defines the process for displaying the virtual objects, the process for updating the display, or the process for moving and updating the virtual objects. For example, it is a display control program for executing display controls such as taking various actions on the displayed information including changing the display mode of the virtual objects, with such events as touch and click on a display object by the user or events detected in accordance with various contexts (situations) such as a lapse of a predetermined period of time as triggers.

As described above, the information provision server 50 provides the information processing apparatus 10 with the virtual object display control data having the following data:

-   -   (1) hyper text markup language (HTML)     -   (2) cascading style sheet (CSS)     -   (3) JavaScript (registered trademark)

The virtual object display control data is data acquired by one URL, and the HTML is acquired in accordance with the access information (URL) selected by the search server 40 on the basis of the beacon transmitter identifier (ID) included in the beacon from the beacon transmitter 20. Further, CSS and JavaSciript referred to by the HTML are acquirable.

That is, the virtual object display control data having HTML, CSS, and JavaScript (registered trademark) as components includes the positional information and guide information on various facilities near one specific beacon transmitter 20 in a real-world three-dimensional space, and is used to display the virtual objects such as the point (POI) position identification marks and the point correspondence registration information explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b) and perform display controls.

The details of the data will be explained later.

(Step S106)

The information processing apparatus 10 uses the positional information on the registration information setting points recorded in the data acquired from the information provision server 50 (virtual object display control data) on the basis of the URL at step S106 and the camera-shot image to calculate the display positions of the point position identification marks on the display screen.

That is, as explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b), the information processing apparatus 10 performs a display position decision process to display the point position identification marks as virtual objects in accordance with the real objects such as the ticket center, the entrance, and the like as registration information setting points in the shot image as the real object.

In the display position decision process, the positional information on the anchors as pre-shot reference images and the registration information setting points in the virtual three-dimensional space recorded in the data acquired from the information provision server 50 (the virtual object display control data), and the camera shot image are used.

The specific steps of the display position decision process will be described later.

(Step S107)

Finally, at step S107, the information processing apparatus 10 displays the point position identification marks in the display positions calculated at step S106, and further displays the facility point correspondence registration information.

The display result is (b) the display image explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b), for example.

Incidentally, in the foregoing process example, the search server 40 provides the access information (URL) for acquiring the information on the neighborhood of the beacon device 20 on the basis of the beacon transferred from the information processing apparatus 10. Alternatively, the search server 40 may be configured to use data other than the beacon.

For example, a thumbnail as a reduced version of an image shot by the information processing apparatus 10 and image feature amount data may be transmitted to the search server 40 such that the search server 40 can determine the position corresponding to the thumbnail and the image feature amount data and provide the access information (URL) for acquiring the display control data for the information on the neighborhood of the determined position.

In this case, the search server 40 is configured to store a correspondence list of the shot images of various locations and the access information in the storage unit. In addition, the shot images are not limited to the images of locations but the images of books or posters. On the basis of the data received from the information processing apparatus 10, the search server 40 selects the shot image including the image matching the data from the correspondence list in the storage unit, and provides the access information (URL) for the POI display control data set in correspondence with the image to the information processing apparatus 10.

Alternatively, the information processing apparatus 10 may read markers or QR codes (registered trademark) recorded in facilities in various locations and transmit the read data to the search server 40 so that the search server 40 can search the database on the basis of the received data and provide the access information (URL) for acquiring the information on the neighborhood of the positions where the received markers or QR codes (registered trademark) are recorded.

In this case, the search server 40 stores a correspondence list of the markers or QR codes (registered trademark) recorded in various locations and access information in the storage unit, performs a data search based on the markers or QR codes (registered trademark) received from the information processing apparatus 10, and provides the information processing apparatus 10 with the access information (URL) recorded in correspondence with the markers or the QR codes (registered trademark).

[3. About a Process for Deciding the Display Positions of Registration Information Setting Point (POI) Position Identification Marks]

Next, a process for deciding the display positions of registration information setting point (POI) position identification marks will be explained.

As explained above with reference to the sequence diagram of FIG. 5, the information processing apparatus 10 acquires the virtual object display control data from the information provision server 50 on the basis of the access information (URL) provided by the search server. Further, the information processing apparatus 10 uses the virtual object display control data and the camera-shot image to calculate the display positions of the point position identification marks on the display screen.

The process for deciding the display position of the point position identification marks executed by the information processing apparatus 10 will be explained below.

FIG. 7 is a diagram illustrating part of HTML data included in the data acquired from the information provision server 50 (the virtual object display control data) on the basis of the access information (URL) provided by the search server.

The HTML data described in FIG. 7 includes the data used by the information processing apparatus 10 to execute the process for deciding the display positions of the point position identification marks.

The data described in FIG. 7 is an example of HTML data used to decide the display positions of the following point position identification marks explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b):

The point A (POI-A) position identification mark 111

The point B (POI-B) position identification mark 121.

The HTML data described in FIG. 7 records a pre-shot reference image and information on relative positions of real objects included in the reference image and registration information setting points.

As described in FIG. 7, the HTML data of FIG. 7 records the following data:

-   -   (1) First reference real object information     -   (2) Second reference real object information     -   (3) Point A correspondence information     -   (4) Point B correspondence information

The reference real object information (1) and (2) will be explained with reference to FIGS. 8(a) and 8(b).

A reference real object is a real object that exists in the real world and is located near the registration information setting point. The reference real object constitutes a reference position for calculating the position of the registration information setting point, and is called anchor or anchor object. The shot image of the reference object is called anchor image. The anchor image is used merely as a reference for calculating the position, and may not necessarily be associated with a POI. However, the anchor image may include a POI. To increase the detection accuracy of the reference position, the images of characteristic objects in the real space are desirably used. In addition, the detection accuracy of the position reference can be further enhanced by using a plurality of anchor images taken in various positions and at various angles in the real space. This enables position detection even when the user terminal is moved or rotated.

Examples of reference real objects will be explained with reference to FIGS. 8(a) and 8(b).

FIGS. 8(a) and 8(b) illustrate real objects of a castle and others existing in the real world.

Coordinate axes (XYZ) illustrated in the drawing are coordinate axes in virtual three-dimensional spatial coordinates defining the positional relationship among the real objects in the real world in three-dimensional positions. They are not absolute positional coordinates like GPS but are local coordinates in which the position of an origin point in the virtual three-dimensional spatial coordinates can be arbitrarily set.

As illustrated in FIGS. 8(a) and 8(b), a first reference real object 201 is a real object composed of an area including the upper part of the castle.

In addition, a second reference real object 202 is a real object composed of an area including the entrance to the castle.

These reference real objects are used to determine whether the reference real objects in the real world correspond to positions in the virtual three-dimensional spatial coordinates, and are used by the user terminal to determine the virtual three-dimensional spatial coordinates and decide the display positions of the point position identification marks in the virtual three-dimensional spatial coordinates.

The information on reference real objects is registered in advance in the HTML data provided by the information provision server 50. Specifically, the reference real object information includes the following information:

-   -   (1) Reference image=shot image of a reference real object         (anchor image) (anchor .png)     -   (2) Positional information on the reference real object included         in the reference image (position: three-dimensional coordinate         data (X, Y, Z) indicative of the position of the reference real         object in the three-dimensional real space)     -   (3) Directional information on the reference real object         included in the reference image (rotation: information         indicative of the posture of the reference real object). The         direction can be generally represented by Euler angle. In this         example, the direction is represented by quaternion (x, y, z; w)         data frequently used in 3D graphics.     -   (4) Area (dimension) information on the reference image         (dimensions: lateral length and vertical length).     -   (5) Conversion of the reference image between coordinate unit in         the virtual three-dimensional space and 3D coordinate unit in         the real space (unit: meter or kilometer).     -   (1) The reference images=the shot images of the reference real         objects (anchor.png) are images 201 p and 202 p illustrated in         FIG. 8(b), for example.     -   (2) The coordinates used in the positional information on the         reference real objects included in the reference images (the         three-dimensional coordinate data (X, Y, Z) indicative of the         positions of the reference real objects in the three-dimensional         real space) are coordinates in a world coordinate system, for         example. The coordinates indicative of the positions of the         reference real objects and the coordinates indicative of the         positions of the point correspondence information are in the         same coordinate space.     -   (3) As for the directional information on the reference real         objects included in the reference images, the directional         information on the reference real objects and the point         correspondence information is directional information with         respect to the same reference point.

In the HTML data described in FIG. 7, the reference real object information on the first reference real object 201 (first anchor information) includes the following data:

-   -   <span type of=‘anchor’>     -   <span property=‘unit’ content=‘1m’/>     -   <span property=‘position’ content=‘152,44,37’/>     -   <span property=‘rotation’ content=‘63,44,99,3.3’/>     -   <span property=‘dimension’ content=‘13,7’/>     -   <span property=‘src’ content=‘anchor1.png’/>     -   </span>

The meanings of the foregoing data are as follows:

-   -   <span property=‘unit’ content=‘1m’/>

This data indicates the data unit and the unit of the subsequent figures is one meter:

-   -   <span property=‘position’ content=‘152,44,37’/>

This is the (2) positional information on the reference real object included in the reference image described above (the three-dimensional coordinate data (X, Y, Z) indicative of the position of the reference real object in the three-dimensional real space).

This data indicates (X, Y, Z)=(152, 44, 37). It is equivalent to the coordinates of the central position of the reference real object, for example.

-   -   <span property=‘rotation’ content=‘63,44,99,3.3’/>

This is the (3) directional information quaternion (x, y, z: w) on the reference real object included in the reference image described above. This data indicates (x, y, z: w)=(63, 44, 99, 3.3).

-   -   <span property=‘dimension’ content=‘13, 7’/>

This is the (4) area (dimensions) information of the reference image (lateral length and vertical length) described above.

Specifically, this data indicates that the first reference image is an image corresponding to a real-world area 13 m wide and 7 m long.

-   -   <span property=‘src’ content=‘anchor1.png’/>

This is the (1) reference image=shot anchor image of the reference real object (anchor1.png).

For example, this is the image 201 p illustrated in FIG. 8(b), for example.

The HTML data described in FIG. 7 further records the following data as the reference real object information on the second reference real object 202 (second anchor information):

-   -   <span type of=‘anchor’>     -   <span property=‘unit’ content=‘1m’/>     -   <span property=‘position’ content=‘173,43,44’/>     -   <span property=‘rotation’ content=‘70,88,34,4.3’/>     -   <span property=‘dimension’ content=‘13,7’/>     -   <span property=‘src’ content=‘anchor2.png’/>     -   </span>

The meanings of the foregoing data are similar to those of the reference real object information on the first reference real object 201 (the first anchor information).

Incidentally, in the example of FIG. 7, there are the two units of reference real object information (anchor information). However, this is an example, and an arbitrary number of units of reference real object information (anchor information) can be recorded in the HTML data.

Further, the HTML data described in FIG. 7 also records information on the registration information setting points, that is, the following registration information setting points illustrated in FIGS. 8(a) and 8(b):

-   -   (a) Registration information setting point A (POI-A) 211     -   (b) Registration information setting point B (POI-B) 212.

Specifically, the following point correspondence information is registered:

-   -   (1) Registration information associated with the registration         information setting points     -   (2) Positional information on the registration information         setting points (three-dimensional coordinate data (X, Y, Z)         indicative of the positions of the registration information         setting points in the three-dimensional real space)     -   (3) Directional information on the registration information         setting points (information indicating the directions of the         registration information setting points from a specific         reference point, for example, the camera having shot the         reference images)     -   (1) The registration information associated with the         registration information setting points is information such as         the point correspondence registration information 112 and 122         explained above with reference to FIGS. 3(a), 3(b), 4(a), and         4(b).

In the HTML data described in FIG. 7, for example, the point correspondence information on the registration information setting point A (POI-A) 211 includes the following data:

-   -   <div type of=‘poi’ resource=‘#poi-a’>     -   <span property=‘unit’ content=‘1m’/>     -   <span property=‘position’ content=“163,43,32’/>     -   <span property=‘rotation’ content=‘34,73,45,4.43’/>     -   <!—html elements of poi-a - - - >     -   </div>

The meanings of the foregoing data are as follows:

-   -   <span property=‘unit’ content=‘1m’/>

This data indicates the data unit and the unit of the subsequent figures is one meter:

-   -   <span property=‘position’ content=“163,43,32’/>

This is the (2) positional information on the registration information setting points (the three-dimensional coordinate data (X, Y, Z) indicative of the positions of the registration information setting points in the three-dimensional real space).

This data indicates (X, Y, Z)=(163, 43, 32). It is equivalent to the positional coordinates of the registration information setting points in the three dimensional real space.

Incidentally, as described above, the coordinates used here are coordinates in the world coordinate system, for example. The coordinates indicative of the position of the reference real object and the coordinates indicative of the position of the point correspondence information are in the same coordinate space.

-   -   <span property=‘rotation’ content=‘34,73,45,4.43’/>

This is the (3) directional information quaternion (x, y, z: w) on the registration information setting points described above. This data indicates (x, y, z: w)=(34, 73, 45, 4.43).

Incidentally, as described above, the directional information on the reference real object and the point correspondence information is directional information with respect to the same reference point.

-   -   <!—html elements of poi-a - - - >

This is (1) the registration information associated with the registration information setting point described above, which is information such as the point correspondence registration information 112 and 122 explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b).

The HTML data described in FIG. 7 further records the following data as point correspondence information on the registration information setting point B (POI-B) 212:

-   -   <div type of=‘poi’ resource=‘#poi-b’>     -   <span property=‘unit’ content=‘1m’/>     -   <span property=‘position’ content=“163,39,28’/>     -   <span property=‘rotation’ content=‘34,70,41,4.53’/>     -   <!—html elements of poi-a - - - >     -   </div>

The meanings of the foregoing data are similar to those of the point correspondence information on the registration information setting point A (POI-A) 211 explained above.

Incidentally, in the example of FIG. 7, there are the two units of registration information setting point (POI) correspondence information. However, this is an example, and an arbitrary number of units of registration information setting point (POI) correspondence information can be recorded in the HTML data.

As described above, the HTML data (the virtual object display control data) acquired from the information provision server 50 on the basis of the access information (URL) provided by the search server records the pre-shot reference images, and the positional information on the anchor objects included in the reference images and the registration information setting points in the virtual three-dimensional space.

Specifically, the HTML data includes the following data:

-   -   the data of the shot reference images of the reference real         objects;     -   the three-dimensional position and posture information including         the positions, directions, and the like of the reference real         objects included in the reference image data; and     -   the three-dimensional position and posture information including         the positions, directions, and the like of the registration         information setting points.

The foregoing information is used by the information processing apparatus 10 to execute the process for deciding the display positions of the point position identification marks.

In the example of FIG. 7, the HTML records the anchor object information and the registration setting point information. Alternatively, the virtual objects and the registration setting point information in the HTML may be recorded in association with each other in JavaScript (registered trademark). Still alternatively, the foregoing information may be acquired as separate data by JavaScript (registered trademark) from the information provision server 50. Therefore, the anchor object information and the registration point information may not be necessarily recorded in the HTML.

The process executed by the data processing unit of the information processing apparatus (user terminal) 10 executes the following process procedure, for example:

The data processing unit of the information processing apparatus (user terminal) 10 inputs from the information provision server 50 the HTML data (the virtual object display control data), that is, the HTML data recording the pre-shot reference images and the positional information on the real objects and the registration information setting points included in the reference images in the virtual 3D spatial coordinates.

Next, the data processing unit detects the same real objects (anchors) in the shot image displayed on the display unit as the real objects included in the reference images. The data processing unit determines the positional information on the user terminal by the use of the three-dimensional positional information on the detected real objects (anchors) and the relative position information recorded in the virtual object display control data. Incidentally, the data processing unit performs a three-dimensional position and posture information analysis process to determine the position of the user terminal from the shot image and the reference images. This process will be described later. Further, the data processing unit calculates the three-dimensional positions of the registration information setting points in the coordinate system with the user terminal as an origin point.

The data processing unit calculates the display positions of the registration information setting points in the shot image displayed on the display unit on the basis of the calculated positional information, and superimposes and displays the point position identification marks as virtual objects in the calculated display positions. For superimposition and display of the virtual objects, the CSS three-dimensional TRANSFORMS function can be used for three-dimensional display.

According to the foregoing procedure, the data processing unit displays the point position identification marks in accordance with the registration information setting points in the shot image.

Incidentally, the process procedure is recorded in JavaScript (registered trademark) acquired by the information processing apparatus 10 from the information provision server 50.

Next, a configuration example of JavaScript (registered trademark) data as one component of the virtual object display control data acquired by the information processing apparatus 10 together with the HTML data described in FIG. 7 from the information provision server 50 will be explained with reference to FIG. 9. JavaScript (registered trademark) is used as a display control program for virtual objects.

FIG. 9 describes part of JavaScript (registered trademark) data acquired from the information provision server 50 on the basis of the access information (URL) provided by the search server.

JavaScript (registered trademark) described in FIG. 9 is equivalent to a processing program recording a process procedure for the information processing apparatus 10 to decide the display positions of the point position identification marks.

The process executed by the data processing unit of the information processing apparatus 10 on the basis of JavaScript (registered trademark) described in FIG. 9 will be explained in sequence according to the process steps (S201 to S209) described in FIG. 9.

(Step S201)

First, the data processing unit of the information processing apparatus 10 inputs a shot image input stream taken by the camera of the information processing apparatus.

The shot image is image data currently input via the camera. The shot image is continuously displayed on the display unit. Incidentally, the shot image explained here means the image shot by the camera function, and may or may not be recorded in the storage unit.

(Step S202)

Next, at step S202, the data processing unit of the information processing apparatus 10 inputs first reference real object information (first anchor information).

The first reference real object information (first anchor information) is the first reference real object information (first anchor information) recorded in the HTML data as explained above with reference to FIG. 7.

That is, the first reference real object information includes the following information on the first reference real object (first anchor):

-   -   (1) Reference image=shot image of the reference real object         (anchor1.png)     -   (2) Positional information on the reference real object included         in the reference image (three-dimensional coordinate data (X,         Y, Z) indicative of the position of the reference real object in         the three-dimensional real space)     -   (3) Quaternion (x, y, z: w) indicative of directional         information on the reference real object included in the         reference image     -   (4) Area (dimensions) information on the reference image         (lateral length and vertical length).

The data processing unit of the information processing apparatus 10 reads the foregoing first reference real object information (first anchor information) from the HTML data.

(Step S203)

Next, at step S203, the data processing unit of the information processing apparatus 10 inputs second reference real object information (second anchor information).

The second reference real object information (second anchor information) is the second reference real object information (second anchor information) recorded in the HTML data as explained above with reference to FIG. 7.

Incidentally, in the example of FIG. 9, the two units of reference real object information (anchor information) are read. However, this is a mere example, and in actuality, all the units of the reference real object information (anchor information) recorded in the HTML data are read.

(Step S204)

Next, at step S204, the data processing unit of the information processing apparatus 10 inputs the registration information setting point A (POI-A) correspondence information.

The registration information setting point A (POI-A) correspondence information is the point A correspondence information recorded in the HTML data as explained above with reference to FIG. 7.

That is, the registration information setting point A (POI-A) correspondence information includes the following information on the registration information setting point A:

-   -   (1) Registration information associated with the registration         information setting point     -   (2) Positional information on the registration information         setting point (three-dimensional coordinate data (X, Y, Z)         indicative of the position of the registration information         setting point in the three-dimensional real space)     -   (3) Quaternion (x, y, z: w) indicative of directional         information on the registration information setting point

The data processing unit of the information processing apparatus 10 reads the foregoing point A (POI-A) correspondence information from the HTML data.

(Step S205)

Next, at step S205, the data processing unit of the information processing apparatus 10 inputs registration information setting point B (POI-B) correspondence information.

The registration information setting point B (POI-B) correspondence information is the point B correspondence information recorded in the HTML data as explained above with reference to FIG. 7.

Incidentally, in the example of FIG. 9, the two units of registration information setting point (POI) correspondence information are read. However, this is a mere example, and in actuality, all the units of the registration information setting point (POI) correspondence information recorded in the HTML data are read.

(Step S206)

Next, at step S206, the data processing unit of the information processing apparatus 10 registers the result of the calculation by the process for determining the position of the camera in the user terminal from the reference images (three-dimensional position analysis process) as the function of JavaScript (registered trademark) (event processing function).

The positioning process before step S206 is performed by the use of the following information acquired at steps S202 to S205:

-   -   (1) The reference image data obtained by shooting the reference         real objects and the three-dimensional position and posture         information including the positions, directions, and the like of         the reference real objects included in the reference image data     -   (2) The three-dimensional position and posture information         including the positions, directions, and the like of the         registration information setting points     -   (3) The shot image input at step S201.

Incidentally, the positioning process (three-dimensional position and posture information analysis process) is performed as a process with the use of simultaneous localization and mapping (SLAM), for example. SLAM is a process for selecting feature points from various real objects included in the camera-shot image and detecting the positions of the selected feature points and the position and posture of the camera. In addition, SLAM is described in Japanese Patent No. 5380789 filed as a prior application by the applicant of the present application.

To perform the process with SLAM, the data processing unit of the information processing apparatus 10 inputs necessary parameters such as the positions, the directions (rotations), and the areas (dimensions) of the display unit (display) and the camera of the information processing apparatus.

The outline of the three-dimensional position and posture analysis process with SLAM is as follows:

First, real objects coinciding with reference real objects are detected from the camera-shot image. This is executed by feature point comparison (feature point matching) of the reference image data on the shot reference real objects acquired from the HTML data and the shot image.

Next, the three-dimensional positions and postures of the shot objects detected from the camera-shot image are analyzed on the basis of differences between the objects included in the reference images and the objects included in the camera-shot image.

The position of the camera having shot the reference images and the current image shooting position (the camera position of the information processing apparatus (user terminal)) do not match, and the objects included in the reference images and the objects included in the camera-shot image are different in direction and size.

These differences are analyzed, and the three-dimensional position and posture of the camera in the real space are analyzed with reference to the shot objects corresponding to the reference objects detected from the camera-shot image.

Incidentally, these analyses are performed by the use of camera setting information such as the lens magnification, the positional and directional information, and angle information of the camera in the information processing apparatus.

Next, the information on the positions, directions, sizes, and the like of the reference real objects recorded in the HTML data, the three-dimensional position and posture information on the camera in the real space, and the position and direction of the registration information setting points (POI) included in the shot image in the virtual three-dimensional space are calculated.

Incidentally, the position of the camera calculated by the foregoing process is represented by the coordinates (Xw, Yw, Zw) of the three-dimensional position camaraPosition in the world coordinate system, for example. In addition, camaraRotation indicative of the direction of the camera and CameraViewAngle indicative of the view angle of the camera are represented by quaternions.

(Step S207)

Next, at step S207, the data processing unit of the information processing apparatus 10 converts the three-dimensional position coordinates of the registration information setting point A (POI-A) and the registration information setting point B (POI-B) into camera coordinates.

The camera coordinates constitute a coordinate system in which XYZ coordinate axes are set for the camera's viewpoint (imaging unit) with cameraPosition and cameraRotation at an origin point in accordance with the direction of the camera.

At step S207, the coordinates (Xw, Yw, Zw) of the registration information setting point A (POI-A) and the registration information setting point B (POI-B) recorded in the HTML data in the world coordinate system are converted into coordinates (Xc, Yc, Zc) in the camera coordinate system from the position and direction of the camera in the world coordinate system obtained by three-dimensional positioning at S206.

(Step S208)

Next, at step S208, the data processing unit of the information processing apparatus 10 converts the camera coordinates of the registration information setting point A (POI-A) and the registration information setting point B (POI-B) into display unit (display) coordinates.

The display unit coordinates constitute a coordinate system in which X axis is set in a rightward direction and Y axis is set in a leftward direction with the upper left corner of the display unit at an origin point, for example. At this step, the registration setting points outside the field of view of the camera are not used in the subsequent display process.

At step S208, the data processing unit converts the coordinates (Xc, Yc, Zc) of the registration information setting point A (POI-A) and the registration information setting point B (POI-B) in the camera coordinate system calculated at step S207 into display unit coordinates (Xd, Yd).

Incidentally, to execute three-dimensional image display, the display unit coordinates are calculated for a left-eye display unit and a right-eye display unit. That is, they are the display unit coordinates (Xdl, Ydl) for the left-eye display unit and the display coordinates (Xdr, Ydr) for the right-eye display unit.

Incidentally, at this step, it is necessary to set a left-eye image and a right-eye image with parallax in accordance with the value of the Z axis (distance) in the camera coordinate system, and a difference according to the parallax between the horizontal coordinates, for example, the coordinate values of Xdl and Xdr is set.

Incidentally, these processes are executed in accordance with a conventional algorithm for three-dimensional image generation process.

(Step S209)

Next, at step S209, the data processing unit of the information processing apparatus 10 displays the point A (POI-A) position identification mark in the display unit (display) coordinate position of the registration information setting point A (POI-A), and displays the point B (POI-B) position identification mark in the display unit (display) coordinate position of the registration information setting point B (POI-B).

These point (POI) position identification marks are the point (POI) position identification marks displayed in the display image explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b).

As described above, the information processing apparatus 10 determines the position and direction of the camera by the three-dimensional positioning process with the use of the HTML data and the JavaScript (registered trademark) data acquired from the information provision server 50 on the basis of the access information (URL) provided by the search server, and calculates the display unit (display) coordinate positions of the registration information setting points (POI) included in the shot image on the basis of the determination result, and displays the point (POI) position identification marks in the coordinate positions.

Further, the registration information on the registration information setting points with the point (POI) position identification marks is displayed near the display positions of the point (POI) position identification marks.

The display positions of the registration information, and the display modes of the registration information and the point (POI) position identification marks, for example, colors, characters, angles, and others can be set in accordance with the CSS regulations as a style sheet received together with HTML data and JavaScript (registered trademark) data from the information provision server 50.

[4. About the Sequence of Processes Executed by the Information Processing Apparatus]

Next, the sequence of processes executed by the information processing apparatus (user terminal) 10 will be explained with reference to the flowchart described in FIG. 10.

The following processes executed by the information processing apparatus 10 will be explained in sequence.

-   -   (1) Process for acquiring the virtual object display control         data and displaying the virtual objects, and a process for         events such as the user's touch (FIGS. 10 to 11)     -   (2) Setting for three-dimensional positioning process (FIG. 12)     -   (3) Process for displaying the virtual objects based on the         detection of an event as a result of the three-dimensional         positioning (FIG. 13)     -   (4) Process for three-dimensional positioning and a process for         notifying the event as a positioning result (FIGS. 14 to 15).

Incidentally, the foregoing processes are all executed by the data processing unit of the information processing apparatus 10. The data processing unit includes the CPU having the program execution function to perform these processes in accordance with the programs stored in the storage unit of the information processing apparatus 10.

Besides, some of the programs stored in the storage unit of the information processing apparatus 10 includes programs received from the information provision server 50, for example, JavaScript (registered trademark).

[4-1. Process for Acquiring Virtual Object Display Control Data and Displaying Virtual Objects]

First, referring to the flowchart described in FIGS. 10 to 11, the sequence of processes for acquiring the virtual object display control data and displaying the virtual objects will be explained.

The steps of the process flow described in FIGS. 10 and 11 will be explained below in sequence.

(Step S301)

First, at step S301, the information processing apparatus performs beacon detection to determine whether a beacon from the beacon transmitter has been received.

When the beacon is detected, the process moves to step S302.

(Step S302)

When the beacon is detected, at step S302, the information processing apparatus requests the search server for the address (URL) for acquiring the virtual object display control data associated with the beacon transmitter.

When making the request, the information processing apparatus transmits to the search server the beacon ID included in the beacon and the identification information (ID) of the three-dimensional positioning method (localization method) supported by the terminal.

(Step S303)

Next, at step S303, the information processing apparatus receives from the search server the address (URL) for acquiring the virtual object display control data associated with the beacon transmitter.

(Step S304)

Next, at step S304, the information processing apparatus displays on the display unit the address (URL) for acquiring the virtual object display control data associated with the beacon transmitter received from the search server. The search server may transmit attribute information such as the title indicative of the display control data as well as the URL, and the information processing apparatus may display on the display unit information easy for the user to understand instead of the URL.

(Step S305)

Next, at step S305, the information processing apparatus determines whether the user has given a display instruction for the address (URL) for acquiring the virtual object display control data and the attribute information such as the title displayed on the display unit.

When the user's display instruction is detected, the process moves to step S306. When it is not detected, the process returns to step S301.

(Step S306)

Next, at step S306, the information processing apparatus activates the web browser and acquires the virtual object display control data accessed by the user in accordance with the specified URL from the information provision server.

Incidentally, as described above, the virtual object display control data acquired from the information provision server is specifically composed of the following data and the like:

-   -   (1) Hyper Text Markup Language (HTML)     -   (2) Cascading Style Sheet (CSS)     -   (3) JavaScript (registered trademark).

The HTML is data indicative of a basic structure of virtual objects to be displayed on the display unit of the information processing apparatus, and is HTML 5, for example.

The CSS is a style sheet that defines the display formats, colors, shapes, and others of the virtual object configuration data defined by the HTML, which is data defining the style of the virtual objects displayed on the display unit of the information processing apparatus.

The JavaScript (registered trademark) is a display control program that defines the process for displaying the virtual objects, the process for updating the display, or the process for moving and updating the virtual objects. For example, it controls various actions such as changing the display mode of the virtual objects, with various events such as touch and click on a display object by the user or events such as a lapse of a predetermined period of time as triggers.

The virtual object display control data is data acquired by one URL. It can be acquired by the access information (URL) selected by the search server on the basis of the beacon transmitter identifier (ID) included in the beacon from the beacon transmitter.

Specifically, the virtual object display control data having components such as HTML, CSS, and JavaScript (registered trademark) includes positional information and guide information on various facilities near the one specific beacon transmitter. It is data for displaying the virtual objects such as the point (POI) position identification marks and the point correspondence registration information explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b) and performing display controls.

(Step S307)

Next, at step S307, the information processing apparatus decides the display positions and the display modes of the virtual objects, and displays the virtual objects on the display unit by the use of the virtual object display control data acquired from the information provision server. Incidentally, this process is performed by the use of a web rendering program and a web page display control program (JavaScript (registered trademark)), for example.

Incidentally, the virtual objects displayed on the display unit are the registration information setting points (POI) position identification marks and the registration information associated with the registration information setting points (POI) explained above with reference to FIGS. 3(a), 3(b), 4(a), and 4(b), for example.

Basic information on these virtual objects is recorded in the HTML data included in the virtual object display control data acquired from the information provision server. The display mode of these virtual objects can be set in accordance with the CSS included in the virtual object display control data similarly acquired from the information provision server.

(Step S308)

Next, at step S308, the information processing apparatus determines the presence or absence of detection of an event as a trigger for updating the display of the virtual objects on the display unit.

The events as triggers for updating the display of the virtual objects include various kinds of events such as the user's touch on the display unit, a lapse of a predetermined time from start of display of the virtual objects, and the movement of the display screen, for example.

What event to be detected to execute display updating is described in the JavaScript (registered trademark) provided by the information provision server, and the display updating is executed in accordance with the description.

Besides, the event detection may be performed in accordance with not only the JavaScript (registered trademark) provided by the information provision server but also the display control program held by the information processing apparatus so that the display updating can be executed in accordance with the detected event.

When any event as a trigger for updating the display of the virtual objects on the display unit is detected at step S308, the process moves to step S309.

(Step S309)

Next, at step S309, the information processing apparatus executes the updating of the display data (virtual objects) as an event process on the basis of the web rendering program and the web page display control program (JavaScript (registered trademark) and the like).

[4-2. Process for Setting Positioning Process Anchor Information]

Next, the sequence of the process for setting positioning process anchor information will be explained with reference to the flowchart described in FIG. 12. The flowchart of FIG. 12 describes a process according to the JavaScript (registered trademark) program which is executed at steps S201 to S206 of the JavaScript (registered trademark) program described in FIG. 9, for example. The objects described in FIG. 12 refer to the objects processed by JavaScript (registered trademark).

The steps of the flowchart described in FIG. 12 will be explained below in sequence.

(Step S401)

First, at step S401, the information processing apparatus acquires anchor objects including the reference images described in the HTML data received from the information provision server. The HTML data can be acquired as document object model (DOM) objects from the JavaScript (registered trademark) program.

As explained above with reference to FIG. 7, the anchor information objects described in the HTML data include the following data:

-   -   (1) Reference image=reference images as anchors (anchor1.png)     -   (2) Positional information on the anchors included in the         reference images (three-dimensional coordinate data (X, Y, Z)         indicative of the positions of the anchors in the virtual         three-dimensional real space)     -   (3) Directional information on the anchors included in the         reference images (quaternions (x, y, z: w) indicative of the         directions in the virtual three-dimensional real space)     -   (4) Area (dimensions) information on the reference images         (lateral lengths and vertical lengths).

(Step S402)

Next, at step S402, the information processing apparatus acquires moving image stream objects from video capture objects taken by the use of the camera function of the information processing apparatus.

(Step S403)

Next, at step S403, the information processing apparatus acquires three-dimensional position determination process (Spacelocalization) objects.

(Step S404)

Next, at step S404, the information processing apparatus sets the moving stream objects acquired at step S402 to three-dimensional position calculation process (Spacelocalization) objects. By steps S402 to S404, the information processing apparatus can process the moving image stream shot by the camera in the three-dimensional position determination process.

(Step S405)

Next, at step S405, the information processing apparatus sets the anchor objects acquired at step S401 to the three-dimensional position determination process (Spacelocalization) shot objects set at step S404, and registers (stores in the storage unit) the same with anchor IDs. Accordingly, the anchor information described in the HTML data is input into the three-dimensional position calculation process.

(Step S406)

Next, at step S406, the information processing apparatus determines whether the process for associating all the anchors with the spatial position determination process objects is completed.

When the process is not completed, the process returns to step S405 to set the anchor objects to the unprocessed data.

When it is determined that the process for associating the anchor objects with the spatial position calculation process objects is completed, the process moves to step S407.

(Step S407)

Next, at step S407, the information processing apparatus registers an event (three-dimensional position result event) processing function for the three-dimensional position determination process (Spacelocalization) objects.

Incidentally, the event processing function is an event that is a trigger for process start as a result of calculation of the position and direction of the camera in the virtual three-dimensional space from the reference images included in the anchor information and the moving image stream shot by the camera in three-dimensional position determination.

Specifically, this is an event processing function that is generated when the image shot by the imaging unit of the information processing apparatus is moved by a predetermined amount (preset defined value) or more due to the movement of the user, the movement of the shooting direction of the camera, or the like, and changes in the position and direction of the camera in the virtual three-dimensional space are detected. When the event processing function is registered at step S407, the process for calculating the three-dimensional position of the camera is started by the use of the three-dimensional position calculation process (Spacelocalization) objects.

Incidentally, the accuracy of event generation according to a predetermined amount of movement, that is, the frequency of the event is recorded in the JavaScript (registered trademark) received from the information provision server. This is set at the time of registration of the event processing function and is input into the three-dimensional position determination processing unit.

[4-3. Process for Displaying Virtual Objects Based on the Detection of a Virtual Object Display Event]

Next, the sequence of a virtual object display process based on the detection of a virtual object display event will be explained with reference to the flowchart described in FIG. 13. The flowchart describes a process according to the JavaScript (registered trademark) program which is executed in the three-dimensional positioning process event function at steps S207 to S209 of the JavaScript (registered trademark) program described in FIG. 9.

The steps of the flowchart described in FIG. 13 will be explained in sequence.

(Step S501)

First, at step S501, the information processing apparatus determines whether an event for the three-dimensional position determination process (Spacelocalization) objects has occurred. This determination corresponds to the determination on whether the event processing function registered at step S407 described in FIG. 12 has been invoked.

When it is determined at step S501 that an event for the three-dimensional position calculation process has occurred, the process moves to step S502.

(Step S502)

When it is determined at step S501 that the event for displaying or updating the virtual objects has occurred, the information processing apparatus acquires at step S502 the position, direction and area (dimensions) of the terminal display unit (display), and the position, direction, and angle of the camera. This step means that the foregoing information is passed as arguments of the event processing function registered as described in FIG. 12.

(Step S503)

Next, at step S503, the information processing apparatus acquires the registration information setting point (POI) correspondence information (three-dimensional position and posture information on coordinates, directions, and the like) described in the HTML data. As described at step S401 in FIG. 12, the registration information setting point (POI) information recorded in the HTML data can be acquired as DOM objects by the JavaScript (registered trademark) program as in the case of the acquisition of the anchor information recorded in the HTML data.

(Step S504)

Next, at step S504, the information processing apparatus converts the three-dimensional position and posture information on the coordinates, directions, and the like of the registration information setting points (POI) acquired from the HTML data received at step S503 from the information provision server into coordinates in the terminal display unit (display) coordinate system, and saves the same in a POI list.

In the conversion process, there are two stages at which the POI coordinates of the positions and postures of the registration information setting points (POI) are converted into the user terminal coordinate system with the user terminal (camera) at an origin point, and then the converted POI coordinates in the terminal coordinate system are further converted into the display device coordinate system.

To convert from the user terminal coordinate system into the display device coordinate system, the position and direction of the camera and the position and direction of the terminal display unit (display) in the virtual three-dimensional space are required. Accordingly, the information acquired at step S502 is used. In particular, in the case of the user terminal in which the direction of the display does not coincide with the direction of the camera, it is necessary to calculate the display positions of the POIs in the display coordinate system with consideration given to the difference in the directions.

(Step S505)

Next, at step S505, the information processing apparatus determines whether the coordinate conversion and the list registration are completed for all the POIs.

When they are not completed, the process returns to step S503 to execute process at steps S503 and S504 on the unprocessed POIs.

When it is determined that coordinate conversion and the list registration are completed for all the POIs, the process moves to step S506.

(Step S506)

When it is determined that the coordinate conversion and the list registration are completed for all the POIs, the information processing apparatus selects POIs in sequence from the generated POI list at step S506.

(Step S507)

Next, at step S507, the information processing apparatus determines whether the coordinates of the POI selected from the list (the coordinates in the display unit coordinate system) fall within the display range of the display unit. Whether they fall within the display range is determined from information on the position and direction of the camera and the position and direction of the terminal display unit (display) in the virtual three-dimensional space. In particular, when the information processing apparatus displays the video from the shooting unit on part of the display unit, the display position of the POI can be calculated in accordance with the display positions of the shot video and the POI can be superimposed in the position of the real object seen in the shot video.

When the coordinates of the POI do not fall within the display range of the display unit, the processing of the POI is stopped and the process returns to step S506 to select the next POI from the POI list.

When it is determined at step S507 that the coordinates of the POI selected from the list (the coordinates in the display unit coordinate system) fall within the display range of the display unit, the process moves to step S508.

(Step S508)

When it is determined that the coordinates of the POI selected from the list (the coordinates in the display unit coordinate system) fall within the display range of the display unit, the information processing apparatus displays the point position identification mark and the registration information of the selected POI at step S508. Incidentally, the display mode of these virtual objects is set by the use of CSS or the like, for example.

(Step S509)

Next, at step S509, the information processing apparatus determines whether all of the POIs are completely processed.

When there is any unprocessed POI, the process returns to step S506 to select the next unprocessed POI from the POI list and execute step S507 and subsequent steps.

When it is determined at step S509 that all of the POIs are completely processed, the process is terminated.

[4-4. Process for Three-Dimensional Position Determination]

Next, the sequence of a camera three-dimensional position determination process will be explained with reference to the flowcharts of FIGS. 14 to 15. The process in these flowcharts is executed not by JavaScript (registered trademark) in the display control data provided by the information provision server 50 but by the program recorded in the recording unit of the information processing apparatus, for example. This makes it possible to avoid the problem that an algorithm for three-dimensional position determination is disclosed by the JavaScript (registered trademark) program, and perform three-dimensional position determination by high-speed processing or the like of hardware in the information processing apparatus at high speed, high accuracy, and low power consumption.

The steps of the flowcharts described in FIGS. 14 to 15 will be explained below in sequence.

(Step S601)

First, at step S601, the data processing unit of the information processing apparatus acquires the resolution of the camera-shot image and the lens magnification of the camera. This step is executed by acquiring the camera setting information recorded in the memory of the camera control unit of the information processing apparatus.

(Step S602)

Next, at step S602, the information processing apparatus initializes a motion sensor attached to the information processing apparatus. Specifically, the information processing apparatus resets the data measured in the past and performs an initialization process to set the current position and inclination (direction) to initial values. The motion sensor is a gyro or an acceleration sensor used to determine the position and posture of the information processing apparatus.

(Step S603)

Next, at step S603, the information processing apparatus extracts feature points from the reference real object information (anchor information) described in the HTML data (see FIG. 7) acquired from the information provision server, that is, the reference images included in the (anchor information) set in the three-dimensional position determination process at step S405 described in FIG. 12.

(Step S604)

Next, at step S604, the information processing apparatus determines whether the process for extracting feature points from the reference images corresponding to all the reference real object information (anchor information) set in the three-dimensional position determination process at step S405 described FIG. 12 is completed.

When there is any unprocessed reference image, the process returns to step S603 to extract feature points from the unprocessed reference image.

When it is determined that the process for extracting feature points from the reference images corresponding to all the reference real object information (anchor information) described in the HTML data (see FIG. 7) acquired from the information provision server is completed, the process moves to step S605.

(Step S605)

When the process for extracting feature points from the reference images corresponding to all the reference real object information (anchor information) described in the HTML data (see FIG. 7) acquired from the information provision server is completed, the data processing unit of the information processing apparatus starts input of the camera-shot image at step S605.

(Step S606)

Next, at step S606, the data processing unit of the information processing apparatus extracts feature points from the frames of the camera-shot image.

(Step S607)

Next, at step S607, the data processing unit of the information processing apparatus acquires observation values of the motion sensor.

(Step S608)

Next, at step S608, the data processing unit of the information processing apparatus calculates three-dimensional position and posture information including the position and direction of the camera in the real space by matching the feature points of the reference images (anchor images) and the feature points of the camera-shot image. This process is executed by the use of the SLAM technique described above, for example.

(Step S609)

Next, at step S609, the information processing apparatus determines whether the three-dimensional position and posture information calculation process by matching the feature points of all the reference images (anchor images) and the feature points of the camera-shot image is completed.

When there is any unprocessed reference image, the process returns to step S608 to process the unprocessed reference image.

When it is determined that all the reference images are completely processed, the process moves to step S610.

(Step S610)

Next, at step S610, the information processing apparatus calculates final three-dimensional position and posture information on the position and direction of the camera in the real space on the basis of the result of matching feature points in all the reference images and the camera-shot image.

At step S608, the camera three-dimensional position and posture information corresponding to one each reference image (anchor image) is calculated, and different camera three-dimensional position and posture information is calculated for the plurality of reference images.

At step S610, for example, the plurality of values is subjected to averaging or the like to calculate the three-dimensional position and posture information including the final position and direction of the camera in the real space. By determining the three-dimensional position and posture with the use of the plurality of anchor reference images, the position determination is enabled even when the user moves or the direction of the camera is changed. In addition, when a plurality of anchors is detected in the camera-shot video, the positioning accuracy can be increased. Further, by combining motion sensors in the terminal, it is possible to estimate the position and direction of the camera even when no anchor is detected in the shot video.

(Step S611)

Next, at step S611, the information processing apparatus detects the amount of change from the three-dimensional position and posture of the camera determined in the previous frame to the three-dimensional position and posture calculated in the current frame is detected. The detection is performed by the use of compensation for motion blur in the frame video resulting from the movement of the camera detected by the motion sensor. By passing the camera posture information and the information on correction of blur in the frame video to the event processing function, it is possible to correct display blur in the case of superimposition on the camera-shot video under control in accordance with JavaScript (registered trademark).

(Step S612)

Next, at step S612, the information processing apparatus determines whether the amount of change detected at step S611 is equal to or more than a predetermined threshold.

The threshold is a value preset from the JavaScript (registered trademark) program in the display control data and saved in the recording unit at step S407 described in FIG. 12.

When it is determined that the position of the image displayed on the display unit has changed by the predetermined threshold or more, the process moves to step S613.

(Step S613)

When it is determined that the three-dimensional position and posture of the camera has changed by the predetermined threshold or more, the information processing apparatus sets the position, direction, and area (dimensions) of the display unit, and the position, direction, and angle information of the camera as a result of the three dimensional positioning posture, and starts a process for event processing function at step S613.

Incidentally, to start the process for displaying and updating the virtual objects, the data processing unit of the information processing apparatus executes the process in accordance with the process flow described above with reference to FIG. 13 and then executes the process for displaying or updating the virtual objects.

[5. About Events as Triggers for Starting Display of Virtual Objects or Updating Display]

In the foregoing example, the change of the position and posture of the user terminal (camera) in excess of the predetermined threshold or the like is explained above as an example of an event as a trigger for the process for displaying the registration information setting point (POI) position identifiers and the registration information corresponding to the registration information setting points (POI) as virtual objects to be displayed on the display unit or the process for updating the display.

However, it is possible to not only superimpose and display the POIs on the real objects seen in the camera-shot video in accordance with the change in the position and posture of the user terminal (camera) as a trigger for the process for displaying virtual objects or the process for updating the display but also implement various display processes and display triggers according to the JavaScript (registered trademark) program by the JavaScript (registered trademark). In addition, the information provider can not only display the POIs in text by the use of the display control functions of HTML and CSS but also provide various display methods.

The data processing unit of the information processing apparatus (user terminal) 10 executes the process for displaying the registration information on the registration information setting points near the information processing apparatus or the process for updating the display with the detection of events according to changes in various predetermined contexts (situations) as triggers.

Specifically, for example, the data processing unit may perform the process for starting or updating display of virtual objects with the detection of events based on the following information as triggers:

-   -   (1) Position of the information processing apparatus (user         terminal)     -   (2) Time     -   (3) Action history of the user having the information processing         apparatus (user terminal)     -   (4) User schedule information registered in the information         processing apparatus or the server     -   (5) User physical information (heartbeat, pulse, and the like)     -   (6) Sale information at stores and others     -   (7) Setting information on the information processing apparatus         (user terminal)     -   (8) Attribute (age, gender, interest, and the like) of the user         of the information processing apparatus (user terminal)     -   (9) Line of sight of the user of the information processing         apparatus (user terminal).     -   (1) Specific example of the process for starting or updating         display of virtual objects with detection of an event based on         the position of the information processing apparatus (user         terminal) as a trigger. One specific example of the process is         as follows, for example:

When the user moves with the information processing apparatus (user terminal), the process for starting or updating display of virtual objects is executed with detection of an event that the distance from the information processing apparatus (user terminal) to the registration information setting point (POI) falls within a predetermined distance (3 m). In this case, in the state in which the position and direction of the information terminal in the real world can be tracked by the three-dimensional position determination process from the reference real object information (anchor information), the positions of the information processing apparatus (user terminal) and the registration information setting point (POI) are measured by the three-dimensional position determination process, and the registration information setting point (POI) may not be necessarily included in the shot video.

Besides, to perform the process, the display control program such as JavaScript (registered trademark) defines a program executing a series of the following operations:

-   -   (a) Measuring the distance from the information processing         apparatus (user terminal) to the registration information         setting point (POI)     -   (b) Comparing the measured distance with a predetermined         threshold     -   (c) Determining the occurrence of an event when the measured         distance becomes equal to or smaller than the predetermined         threshold.     -   (2) Specific example of the process for starting or updating         display of virtual objects with the detection of an event based         on time as a trigger will be explained. One specific example of         the process is as follows, for example:

For instance, when the user of the information processing apparatus (user terminal) is in the neighborhood of a restaurant at 11:00 am at which the restaurant is opened, the position of the restaurant, the menu of the restaurant and others are displayed as virtual objects.

Besides, to perform the process, the display control program such as JavaScript (registered trademark) defines a program executing a series of the following operations:

-   -   (a) Measuring the distance from the information processing         apparatus (user terminal) to the registration information         setting point (POI)     -   (b) Comparing the measured distance with a predetermined         threshold     -   (c) Acquiring the current time     -   (d) Determining the occurrence of an event when the measured         distance becomes equal to or smaller than the predetermined         threshold and at the time for opening the registration         information setting point (POI) (for example, the restaurant).

In addition, the information provision server provides the information processing apparatus with the registration information setting point correspondence registration information including the menu of the restaurant and others as virtual objects.

-   -   (3) Specific example of the process for starting or updating         display of virtual objects with detection of an event based on         the action history of the user of the information processing         apparatus (user terminal) will be explained. One specific         example of the process is as follows, for example:

The movement state of the user of the information processing apparatus (user terminal) (walking, running, or high-speed movement by car, train, or the like) is analyzed and optimum information according to the analysis information is displayed as virtual objects.

When the user is walking, for example, route information, seeing spot guide information, rest room location information, and the like according to the movement position and speed are displayed as virtual objects.

Besides, to perform the process, the display control program such as JavaScript (registered trademark) defines a program executing a series of the following operations:

-   -   (a) Measuring the distance from the information processing         apparatus (user terminal) to the registration information         setting point (POI)     -   (b) Comparing the measured distance with a predetermined         threshold     -   (c) Determining the occurrence of an event when the measured         distance becomes equal to or smaller than the predetermined         threshold.

In addition, the information provision server provides the information processing apparatus with the route information, seeing spot guide information, rest room location information, and the like as virtual objects.

-   -   (4) Specific example of the process for starting or updating         virtual objects with detection of an event based on user         schedule information registered in the information processing         apparatus or the server as a trigger will be explained. One         specific example of the process is as described below, for         example.

To perform the process, it is necessary to register the user schedule information in advance in the memory of the information processing apparatus or the information provision server.
